Five identical resistors each of resistance 1 Ω Ω are initially arranged as shown in the figure by clear lines. If two similar resistances are added as shown by the dashed lines then change in resistance in final and initial arrangement is

Text Solution
Verified by ExpertsThe correct answer is:
A
initial R eq = 5 Ω Ω

final R eq = 3 Ω Ω
change in resistance = 5 – 3 = 2 Ω Ω
